Manage winrm settings with wsman provider

Windows PowerShell Blog — Tue, 06 Jan 2009 20:57:00 GMT

PowerShell remoting is built on top of Windows Remote Management (WinRM), which is Microsoft’s implementation of WS-Management protocol. You can use winrm.cmd command line tool to query and manage winrm settings. PowerShell V2 CTP3 contains a wsman provider for you to manage winrm settings with the standard *-Item cmdlets .

Revisiting Old Posts: Get-Process | Dir (about ValueFromPipelineByPropertyName)

Windows PowerShell Blog — Mon, 05 Jan 2009 09:54:03 GMT

A number of PowerShell MVPs and PowerShell team members are helping me to compile a table of contents for our blog, which basically means that I’m getting to go back and revisit all of the fun stuff posted to the PowerShell blog over the past few years.

I’d like to know whether you find this format useful or not and then specific feedback about how to make the screencast better (e.g. I recorded it at 1024x768 - is that good or too large?).

Using PowerShellPlus with PowerShell V2 (CTP3)

Tobias Weltner — Sun, 04 Jan 2009 21:54:00 GMT

The great news is: PowerShellPlus works as-is with PowerShell V1 and PowerShell V2, indicating the stable and solid approach of its engine. No updates needed. From the very beginning, we took care to use only approved and backwards-compatible PowerShell APIs.

You don't use PowerShellPlus yet? It is an awesome interactive console and PowerShell editor, and you should really try it! It is derived from famous "PowerShellIDE" which was the world's first PowerShell GUI, editor and debugger (surfaced June 2006). Yet again, it pays off to have solid 4 years of experience in this product.

There are a couple of things you should know when you just upgraded from V1 to V2 to get PSP to recognize the new V2 features.

Update the Cache

For speed purposes, PowerShellPlus caches information regarding available Snap-Ins and Cmdlets. So when you have been using PSP on PowerShell V1 for a while and upgrade to PowerShell V2 CTP3, things continue to work as expected except all new V2 specific Cmdlet parameters and help pages are still missing.

Normally, PSP detects at startup all freshly added Snapins and adds them to its cache. Upgrading PowerShell is a whole new ballgame though because actually no new snapins is added. Instead, existing snapins are updated.

To manually reset and update PSPs internal cache, do this:

Launch PowerShell Plus
Hold down SHIFT when the splash screen opens to open the startup management dialog
Check the option "Clear cached Cmdlet info", then click OK
PSP starts and re-examines all available snapins. This may take a minute or two, and you will see a green bar with progress information. Once the green bar is gone, you are all set.

Once you cleared and updated the cache, try this:

Get-WMIObject -

Code completion will show the complete list of V2 parameters.

Update the Learning Center

If you'd also like to update the learning center help pages, keep this in mind: the procedure you just executed automatically adds all new help topics to the learning center. It does not update existing topics though. So to update the learning center, simply delete its cache before you do the procedure above ("Yeah, thanks for telling me now! Just did it!" - oh well, ok, just do it again)!

How do I clear the learning center cache? For example like this:

del $env:localappdata\PowerShellPlus\manpages\*.htm -whatif

(Remove the -whatif if you are confident you typed in the correct line)

What's Next?

Of course there are plenty of additional extras in PowerShell V2 like block comments and inline code. We will support them with one of our next maintenance releases but for now, isn't it good to know that PowerShellPlus runs beautifully with PowerShell V2 CTP3?

Cheers

-Tobias

Extending and/or Modifing Commands with Proxies

Windows PowerShell Blog — Sun, 04 Jan 2009 16:55:00 GMT

There are so many powerful features in V2, it is hard to know where to begin. This one is going to blow to top of your head off when you understand what it enables you to do.

How To Write a Console Application in PowerShell with Add-Type

Windows PowerShell Blog — Sat, 03 Jan 2009 00:26:56 GMT

Windows PowerShell CTP3 has a lot of very cool things. CTP2 introduced the Add-Type cmdlet, which allowed you to dynamically compile C# in PowerShell. It was actually possible to use the CompilerParameters to Add-Type to make a console application, but it wasn't particularly easy. In CTP3, we've made this a lot easier to do.

How and Why to Use Splatting (passing [switch] parameters)

A Module to Create Modules and Advanced Functions

The reason for this is that these mechanisms are critical technologies to support SHARING.
